Application filed January 25, 1913. SeriaI'No. 744,063.

To all? whom "it may concern Be it known that I, ROBERT D. BUTLER, asubject of the King of Great Britain, residing at Yarmouth, Province ofNova Scotia, Canada, have invented 'certain'new and useful Improvementsin. Sliding Hinges for Engine-Hoods; and I do hereby declare that thefollowing is a full, clean-and exact description of the invention, suchas will enable others skilled in the art to which it appertains to makeand use the same.

The invention to be hereinafter described relates to sliding hinges.

In order to more clearly disclose the construction, operation, and useof the invention, reference should be had to the accompanying drawingsforming part of the present application.

Throughout the several figures of the drawings like reference '01]aracters designate the same parts.

In the drawings: Figure 1 is a top plan view of a cover for the motor ofa motor boat, embodying my invention; and Fig. 2 is a sectional view,taken on line 22 of Fig. 1.

The main object of this invention is to provide means whereby a covermay be quickly and easily raised and slid out of the way, and also toprovide means whereby the cover may be secured in any vertical orforward position desired; these results are obtained by the constructionand combination of certain parts hereinafter set forth.

The cover 1 for the motor of a motor boat of the usual rounded form, andconstruction is provided with a metal tab 2 secured to the underneath ofthe front central part of the said cover 1 by screws 3, or othersuitable means. The forward end of the said tab 2 is bent into a sleeve4:, loosely mounted around the rod 5 which connects the sleeves 6, whichare slidably mounted on the two parallel rods 7. Thesaid rods 7 areparallel with and a little above the deck 8. The inner ends of the rods7 are secured in the wall 9 of the engine pit in any suitable manner,and their forward ends are bent so as to be vertical, and passed throughthe deck 8. The said forward ends are secured in place by screws 10threaded therein, in combination with a supporting plate 11 secured tothe under face of the deck 8, as in Fig. 2, or by any other suitablemeans.

A block 12 is secured to each side of the engine pit with its outer facein the same vertical plane as the outer face ofa-nother block 13 securedto the inside of the cover 1, above the said block'12. Rods 1 1 havingtheir inner upper ends 15 and their outer lower ends 16 pivotallysecured to the upper and lower blocks respectively by means of studslZand bolts 18,- respectively, area-provided. The said bolts 18 areprovided with hand screws 19 for the purpose of adjustment of the cover,as will be explained.

The operation is as follows: Assuming the cover to be over the motor asin Fig. 1, to remove the cover from over the pit, the back part of thecover is lifted, the lift taking place in a forward arc with its radiusequal to the distance between the centers of the studs 17 and bolts 18,the bolts being the pivotal point. Of course, if the back of the covertravels in a forward arc, the front of the cover must travel forwardalso; this is accomplished by the tab 2 revolving on the rod 5, as itsangle to the horizontal plane changes and at the same time pushing thesleeves 4 and 6 forward along the rods 7. As soon as the rods 14: havepassed the vertical position, it is obvious that the cover will fallforward of its own accord, until it rests on the deck 8. If it bedesired to se cure the cover 1 in a position not all the way open, thismay be accomplished by tightening the hand screw 19 against the lowerends 16 of the rods 14, so as to bind the said ends against the blocks12. Fig. 2 shows in dotted lines, the cover secured in this manner, in aposition not quite entirely open. It is thought that the operation willbe clearly understood from Fig. 2; in which the arrows indicate thedirection of movement of the several most important elements during theopening or removal of the cover.

Though shown as applied to the cover of a motor boat, this device may ofcourse be used for any other suitable purpose, and I do not in any waylimit myself to this one use, only a preferred form being illustrated inthis application.

It is thought that the construction, operation, and use of the inventionwill be clear from the preceding detailed description.

Changes may be made in the construction, arrangement, and disposition ofthe several parts of the invention without in. any way departing fromthe field and scope of the same, and it is meant to include all andswinging connections between the sleeves and the cover.

3. In combination; a cover;fixedly mounted, horizontal, parallel rods,contiguous to the front end thereof; sleeves slidably mounted on thesaid rods; and swinging connections between the front end of the coverand the sleeves.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.

ROBERT D. BUTLER.
